docs(issue-5): phase 2b scenarios, operations note and task checklist
Three scenarios join the contract set, so the fifteen vectors now cover an unproven side effect, an undecidable attribution, and an agent whose state goes unreadable in the window between finalization and notification. All fifteen match their expected decision. The side-effect case needed a decision about layering. Authoritative enforcement belongs in manifest verification, which has the job record and therefore knows what was declared; the policy honours an explicit negative from the collector so the case is expressible as a vector. Absence is not read as proof there, because the manifest check is the layer that fails closed on missing evidence. The operations note records why the agent declares and the reader re-derives, the three gates and why the backend allowlist can only be narrowed, the notification transaction, and the rollback. It also records a deviation from my own plan. §D2 asked for reviewer sign-off before promoting an attempt id into the record, since that changes a contract phase 1 froze. Measurement during implementation showed the change was not needed: the attempt guard already lives in the evidence layer, where attempt identity actually is, so auto-completion passes the engine a status precondition instead. The schema is untouched, the frozen contract holds, and a characterization test fails the moment a record starts carrying an attempt id, which is when to revisit it.

fix(issue-5): address phase 2a round 2 findings (F-C, F-D, R1, R4)
Both reviewers sustained the round 1 fixes and found four more. Each was reproduced here before being accepted; none were rebutted. F-C (claude, blocking) -- my own round 1 fix caused this. Making refused writes exit non-zero also classified an idempotent ACK as a refusal, and the wrapper finalises an approved job with `status --set completed` on a record that is already completed. It runs under `set -e`, so the *success* path aborted with exit 4 before its validation hook and its final stdout line. Reproduced at the shell. An idempotent result is now distinguishable from a refusal and exits 0; a genuine conflict still exits 4. F-D (claude) -- routing the operator write around update_status dropped the status vocabulary check. Under the rollback flag an invalid status was written to the record with exit 0, where before it was refused with exit 1 and the record left alone. The check now runs first, in both modes. R1 (codex, blocking) -- the previous fix compared identifiers only when they happened to be present, so evidence carrying none at all was still approved on the dispatch record's own flags. That is the self-assertion the check exists to replace. Every identifier must now be supplied and agree, and a report manifest must associate with the attempt being judged. Identifiers are read from a collector envelope beside the payload rather than from inside it: a native Herdr payload may not carry MAM fields, so one appearing there is either fabricated or a contract violation, and either way it is not evidence. R4 (codex) -- a sequence number orders nothing unless the compare and the write are atomic. Two flushes could both read the old value, the newer land first, and the slower overwrite it. Reproduced deterministically. The mirror now serialises read-compare-write under a per-job audit lock, taken outside the registry transaction so a slow mirror still cannot lengthen it, and each write uses its own temp file instead of a shared name. All eight new regressions fail against the pre-fix code. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UrDNJkHmm18uu7n7JwV5Qd |

fix(issue-5): address phase 2a cross-review findings (F-A, F-B, R1, R2, R3)
Two reviewers raised five defects. Every one was reproduced here before being accepted; none were rebutted. F-A (claude, blocking) -- the CAS table had no row for two transitions the wrapper legitimately makes, so `submit --type loop|discuss` silently stopped working by default: the per-iteration re-dispatch was refused and its metadata discarded, the exhausted-budget finalisation was refused, and the CLI returned 0 both times. Reproduced against the real modules. Fixed by naming those transitions rather than carving an exception: `redispatch` and `finalize` are requests gated on operator authority, so the wrapper can move a finished record while an agent still cannot touch its own terminal. A re-dispatch must advance the iteration, so a replay cannot resurrect a job. The operator CLI now exits non-zero with a reason when a write is refused -- the silence is what let this hide. F-B (claude) -- moving the audit mirror out of the lock made status.json last-writer-wins, so a slow flush could leave it behind the registry. It now carries transition_seq and skips a write that would go backwards, restoring the sequential consistency the lock used to provide for free. R1 (codex, blocking) -- the policy called attribution with only the dispatch record, so it proved the record was well-formed and never confronted the identifiers the evidence carried. A finalized scenario with a different session, a different attempt and a manifest from another attempt was still approved. Observed identifiers are now collected from the timeline and every one must agree; a manifest belonging to another attempt holds. Collecting every occurrence rather than the first matters, because taking the first would drop exactly the contradicting value this is meant to catch. R2 (codex, blocking) -- a supplied expected_attempt was ignored when the record had no attempt field, so a compare-and-swap with nothing to compare committed. It now fails closed, which matters because 2b plans to gate inferred completion on precisely that precondition. R3 (codex) -- a status could ride in as an ordinary field, so `progress` could commit a terminal from inside the boundary that exists to prevent it. Status is now settable only by the request that owns it, unknown requests are refused, and pending has an owning request instead of being an untyped merge. Each of the eleven new regressions was checked against the pre-fix code first.

feat(issue-5): shadow watcher that logs would-complete and cannot write
policy.decide is a pure function so the phase-0 scenario fixtures can be fed to it verbatim. Those seven decisions survived three-reviewer scrutiny, so they are the contract rather than a fresh set of rules, and the test asserts against expected_policy.decision directly. Order inside the policy matters. Transport doubt and staleness invalidate the evidence itself, so they are answered before anything is inferred from it; a blocked agent is waiting for a human and can never be completed; attribution including the execution anchor comes before quiescence, because idle is not evidence of finishing when a session is reused; and a report must be finalized, never merely paused, since a debounce is a candidate filter and not an authority. The shadow runner is never handed the engine, so it has no route to a write. That is the structural half of P2A-03. The measured half hashes every file under the registry directory around a full run and asserts it is unchanged, which is a stronger claim than checking a status field. Adds the five scenarios P2A-04 requires: a raced double dispatch, a reused attempt with no anchor, a mid-write report, an unknown status, and a pane restarted mid-flight. They pass phase 0's own fixture validator, which is what keeps them honest. The phase-0 test that pinned exactly seven scenarios now requires the seven to still exist rather than forbidding growth. Also pins the two phase 1 handoffs as dormant: nothing here spawns a daemon, so preexec_fn stays unreachable, and nothing calls a frozen shell helper.
